bit of a vague warning though by the americans seeing as the attack didnt really come from the sea.

The US warned India about a possible threat at least a month before last week's Mumbai attacks, US media have quoted unnamed officials as saying.
One official said India had been told of an apparent plot to launch an attack from the sea, the AP agency reports.
The reports came as India's navy chief said there had been "systemic failures" in the country's security and intelligence services.

An Indian official appeared to confirm the US media reports that there was a known threat to at least some of the locations targets, including the Taj Mahal Palace Hotel.

Mumbai police chief Hassan Gafoor told a news conference on Tuesday that they had "had an alert that hotels like Taj could be exposed to such danger".
ABC News quoted Indian officials as saying that after receiving the US warning, they also intercepted a satellite phone message on 18 November warning of a sea-borne attack on Mumbai.
